So, I was planning to start the thickness sander I decided to build, but just wasn’t in the mood. Instead I decided to see if I could improve on the dmt sharpness. The good news, I did. The bad news, I did. It’s not a tremendous amount, and not enough to make me go back to waterstones, but I will leave my hard arkansas on the bench from now on.

I may blog this but long story short,

With just the 3 micron dmt

Polishing the back on the felt wheel with green compound and sharpening with the hard arkansas stone ( I saw a slight difference from the dmt to the arkansas)

Same sequence….

I did this with 4 different hand planes. The 2 shown, the Stanley #18, The sargent 710, and a Bedrock 604 and a Stanley 60 1/2.

All showed a subtle difference. The biggest difference was with the polishing of the back. Sharpening the bevel was barley distinguishable but I could see a slight difference in the resistance.

If, from the dmt, you polished the back with the felt, then sharpenend with the dmt, the difference would be almost unknoticable from sharpening with the arkansas. I’d have to do it a few more times to really know for sure, but my gut tells me the arkasas would have a slight edge.

Also note, this is a piece of Red oak, not some nice easy piece of cedar.
